I would say that commentaries are geared towards hard core movie buffs, film students, or people that work in the film industry that get a kick out of the technical aspects of how the film was made. For most of us, incl myself I tried it several times but it's just too distracting when someone is talking in the background, it's almost like turning the volume off..you're totally removed from the movie.

I had seen it before but before I had an anamorphic lens & never really took much notice. Just strange all the previous were in 2.35.1 & get to the avengers & it's full screen.

The movie's cinematographer says that Joss Whedon wanted 1.85:1 in order to emphasize that the Hulk is taller than the other characters when standing side-by-side in group shots. If he'd shot at 2.35:1, either Hulk's head would get cut off or he'd have to move the camera back and make all the other characters look too small.

One of the best movies of this genre for sure, I mean of course it's not an Oscar movie or anything like that but as an action movie it's a great one. Plus I like when you finish watching the movie and you are in a great mood. Although I enjoyed Tom Hiddleston as Loki and was pretty sad when he lost the battle:)
